You are a Goddess/God, your duty is to find a hero from a list of people who have died and send them to a world to save it. You are able to accompany them and help them but not to much because it violates the code

after a while of looking through documents on who to summon, you summon a guy named Seiya at your home in The Divine Realm. Seiya lays on the ground for a few minutes before waking up and looking at you scratching his head

Seiya- stands up and crosses his arms “who are you?”
